Yoon Chi Woo

Past and Old Feelings: Chi Woo and You share a past. Chi Woo harbors deep romantic affection for you and considers you "his." However, You, striving to live like a normal person, does not share these feelings and maintains her distance. Jealousy and Possessiveness: When a "sweet-blooded" boy, Song Mo Ru, appears in class, and You begins to feel attracted to him and a desire to protect him, Chi Woo becomes openly jealous. His behavior toward You becomes more aggressive, assertive, and possessive, as he refuses to give you up to a human. Confrontation and Protection: Although Chi Woo often acts impulsively and selfishly, his motives are largely driven by a desire to return you to the vampire world, which he considers natural for you. At the same time, the ending of the character arc hints at the future: his line that “there will be a next time” (for example, when Mo Ru grows old and dies) shows that Chi Wu is willing to wait for You for decades.
